It contains the vestibular folds, and between these and the vocal folds are the laryngeal ventricles. [1] The vestibule is an opening in the lateral wall of the larynx, between the vestibular fold above and the vocal folds below. It is the inlet to another cavity in the lateral wall of larynx, the laryngeal ventricle.
The rima vestibuli is a space in the laryngeal cavity. It is to the vestibular ligaments (vestibular folds once covered with mucous membrane) what the rima glottidis is to the vocal ligaments (vocal folds once covered with mucous membrane) – the space formed when the folds are separated. It can be defined as the space in between the false ...
The laryngeal ventricle, (also called the ventricle of the larynx, laryngeal sinus, or Morgagni's sinus) [1] is a fusiform fossa, situated between the vestibular and vocal folds on either side, and extending nearly their entire length. There is also a sinus of Morgagni in the pharynx.
The vocal folds are located within the larynx at the top of the trachea. They are attached at the back to the arytenoid cartilages, and at the front to the thyroid cartilage via Broyles ligament. They are part of the glottis. Their outer edges are attached to muscle in the larynx while their inner edges form an opening called the rima glottidis.
The vestibular fold (ventricular fold, superior or false vocal cord) is one of two thick folds of mucous membrane, each enclosing a narrow band of fibrous tissue, the vestibular ligament, which is attached in front to the angle of the thyroid cartilage immediately below the attachment of the epiglottis, and behind to the antero-lateral surface of the arytenoid cartilage, a short distance above ...
Laryngologists treat disorders of the larynx, including diseases that affects the voice, swallowing, or upper airway. Common conditions addressed by laryngologists include vocal fold nodules and cysts , laryngeal cancer , spasmodic dysphonia , laryngopharyngeal reflux , papillomas , and voice misuse/abuse/overuse syndromes.
The rima glottidis is the narrowest part of larynx. It is longer (~23 mm) in males than in females (17–18 mm). [1]The rima glottidis is an aperture between the two true vocal cords anteriorly, and the bases and vocal process of the two arytenoid cartilages posteriorly.
The laryngeal saccules are extensions of the laryngeal ventricles as part of the lateral wall of the larynx. [1] They ascend posterior to the thyroid cartilage. [1] They are surrounded by loose areolar connective tissue. [1] This may contain lymphoid tissue, which is healthy in children and may be a sign of illness in adults. [1]
